The term flashpoint refers specifically to the temperature at which the vapors of a material can ignite in the presence of an ignition source. It is a critical measure in fire safety because it helps determine the flammability of various substances. Knowing the flashpoint of a material is essential for safe handling, storage, and transportation, as it indicates the risk of fire.

When the temperature of the material rises to its flashpoint, enough vapor is generated to ignite when exposed to an open flame or spark. This property is particularly important in industries dealing with flammable liquids, as it directly affects safety protocols and emergency response strategies.

In contrast, the other options describe different safety parameters that do not accurately capture the specific definition of flashpoint. For instance, the concept of needing a fire extinguisher relates to fire readiness, while the minimum safe storage temperature and ignition temperature may involve different contexts or thresholds that aren't synonymous with flashpoint. Understanding these distinctions helps ensure appropriate safety measures are implemented based on the characteristics of hazardous materials.
